This list shows all the encryption algorithms that can be used during a session with a remote server.
If set to encAny, wodSSHTunnel will try to use the AES encryption algorithm first, if it is supported by the remote server.

DES encryption cannot be used with SSH2 as it has been proven to be unsafe. SSH1 still supports it, although usage of Blowfish is suggested.

AES encryption cannot be used with SSH1 because the protocol specification doesn't support it.
